1. A transport device for transport of loads suspended on raised tracks with respect to the ground surface, the tracks comprising a first track and a second track arranged parallel to one another and defining the transport and transfer path of the suspended loads, the transport device comprising:
a container for containing internally thereof materials to be transported,
a support structure of the container, having a shape such as to have a first longitudinal side and a second longitudinal side that are parallel to one another,
the container being coupled to the support structure in such a way as to be arranged below the support structure at a central opening present in the support structure,
movement means, for movement of the support structure, and therefore of the container, along the tracks, the movement means consisting of a first motorised wheel and a second motorised wheel wherein:
the first motorised wheel is mounted at the first longitudinal side of the support structure so as to be in contact with a first track and the second motorised wheel is mounted at the second longitudinal side the support structure so as to be in contact with a second track, when the transport device is positioned on the tracks;
the first motorised wheel is rotatably mounted about an axis of rotation perpendicular to the first longitudinal side of the support structure and the second motorised wheel is rotatably mounted about an axis of rotation perpendicular to the second longitudinal side of the support structure,
the first motorised wheel and the second motorised wheel are predisposed on the support structure so that the relative axes of rotation are coaxial to one another and are activatable in rotation independently of one another,
stabilising means comprising at least a first idle rolling element and at least a second idle rolling element, wherein:
the first idle rolling element is coupled to the support structure so as to be arranged in such a way as to be in contact with the first track when the transport device is positioned on the tracks and to be able to roll on the first track when the transport device is moved along the tracks,
the second idle rolling element is coupled to the support structure so as to be arranged in such a way as to be in contact with the second track when the transport device is positioned on the tracks and to be able to roll on the second track when the transport device is moved along the tracks,
the first idle rolling element and the second idle rolling element are coupled to the support structure in such a way as to be arranged on opposite sides with respect to the coaxial axes of rotation of the first motorised wheel and the second motorised wheel,
and in that the first idle rolling element is coupled to the support structure so as to be pivoting about an axis parallel to the first longitudinal side of the support structure and perpendicular to the first track and that the second idle rolling element is coupled to the support structure so as to be pivoting about an axis parallel to the second longitudinal side of the support structure and perpendicular to the second track.
